I search a lot. Heavy heavy searching. Kagi's no-BS approach to search gets me to relevant results much faster than any other search engine. And the ability to down-rank or block unreliable sources only sharpens that experience.
I have used, and continue to try on occasion to keep my opinions updated, all the big search engines. DDG, Bing, and Google. The search experience is really not there for me in those 3. Bing consistently produces poor results, DDG is a bit better but I still have to manually sift through poor quality results to get what I want, and Google makes me scroll past a lot of bloat and ads first to get to quality results, with more ads interspersed throughout.
I like being able to search, get my quality results, and move on with my life. That's worth paying for to me.
